Spectrum Tube Power Supply (EHV)
$445.00 excl. GST
Extra high voltage power supply & tube support for operating standard spectrum tubes. Complete with recessed tube support, socket, support pillar and switch. Tubes not included.
Spectrum tubes are special long thin discharge lamps (sometimes called Geissler tubes or Capillary tubes) which, during manufacture, are filled with certain specific gases. When electric current is passed through the gas, the discharge glows and a certain set of known wavelengths of light is emitted and is used for optical experiments. The voltage required to force the gas to conduct electric current is very high (several thousand volts) but, once conduction begins, a much lower voltage is required to maintain the current flow. This power supply provides these conditions.
Features of the IEC SPECTRUM LAMP POWER SUPPLY & STAND:
• SAFE: Designed to proper engineering standards of electrical safety.
• COMPACT: The unit takes very little space in the lab.
• EASY TO USE: Power is applied by a single illuminated rocker switch on the front panel. The special adjustable stand supports the tube in the vertical position.
